Was looking through holiday snaps on DP phone and found a couple of photos in the deleted file that were of a night out (couldn't see any faces, they were clearly taken accidently, but I could tell the scene was a club). DP was right next to me so I showed and asked when this was and he went bright red and couldn't get his words out. He then said it was for a friends celebratory drinks and it was a couple of weeks ago when we had had a fallout which is why he didnt say anything. I left it at that, but he kept going on about it. Now I'm wondering if there is something dodgy about it. I dont like night outs (I'm boring, haha) so its not as if he didn't tell me because he thought I'd invite myself and didn't want me there. A couple of years ago at the beginning of our relationship, he messaged a girl online and sent her a few flirty messages. He didnt know the girl, on this particular day I'd completely shut off and he said the lads egged him on and he regretted it right away etc. I never would've known about this had the girl not messaged me , I don't think he would ever have said anything had he not been caught out. I'm wondering wether something similar has happened this time
